4 Claims.

My invention relates broadly to windows and more particularly to an improved arrangement of hardware for converting existing double hung window sashes vinto a swinging reversible sash window.

One of the objects of my invention is to provide an improved construction of hardware which may be applied to double hung window sashes for converting such windows into swinging reversible sash windows.

Another object of my invention is to' provide a simplified construction of double hung reversible window sash arrangements in which standard sliding sashes are converted intoY sliding and swinging sash arrangements with simplied hardware for maintaining the sashes in a particular tilted position.

Still another object of my invention is to pro- Vide a simplied arrangement of combined Weather strip and latch for tiltable double hung slidable windows in which the latch becomes effective to maintain the sashes of the window in particular angular positions as the sashes are tilted in selected vertical positions.

Still another object of my invention is to provide a construction of pivot means for the swinging sashes of a double hung window in which the pivot means becomes effective to maintain the tiltable sashes in a particular position to which the sashes are moved before tilting.

A further object of my invention is to provide a construction of hardware for double hung slidable sashes of tiltable Windows wherein pivot means are provided which become effective to grip the side frames of the window in the position in which the sashes are tilted for maintaining the sashes in such selected position.

Other and further objects of my invention reside in the construction of improved hardware for double hung reversible window sashes with associated interlocking weather stripping in which:

is a vertical sectional view taken through the metallic insert of Fig. 20 on line 2I--2l thereof and Fig. 22 is a transverse sectional View through the metallic insert of Fig. 20 on line 22-22 thereof.

My invention is directed to a simplied arrangement of hardware for converting existing double hung window sashes to swingable or tiltable window sashes. rEhe hardware is readily installed either in existing double hung slidable windows or supplied with new installations of sashes in building construction. In applying the hardware of my invention to existing double hung window sashes, the upper and lower sashes are removed from the window frame and the sashes cut down at each side thereof approximately onehalf to three-fourths of an inch. A narrow slot or groove is then mortised into the edge of each sash for receiving a prcjectable and retractable weather stripping, an operator therefor and a central pivoted guide. A longitudinally extending strip extending the length of the sash is then applied at each side of the sash. The strip serves as a connector for the sash cords, a coacting weather strip element and as a carrier for the hardware constituting the pivoted means for the sash. The strip carries a liner in the form of a recessed cup which has a diametrically extending slot therein aligned with the coacting weather strip groove in the sash strip` The liner serves as a bearing means for cam members carried by the hardware constituting the pivoted means for the sash. When the sash operates in a vertical sliding direction the cam members are aligned with the diametrical slot in the liner permitting vertical sliding movements of the sash. However, when the sash is moved to a selected position with respect t-o the window frame and then angularly tilted the cam members of the hardware slide against the faces of the liner projecting the hardware transversely at opposite sides of the sash gripping the sides of the window frame and maintaining the sashes in a selected tilted position.

Referring to the drawings in detail, re'erence character i designates the lower sash and reference character 2 designates the upper sash of a double-hung window, in which the sashes are slidable in stiles 3 and Q, with sash strips 5 and 5 guided by the stiles. The opposite extreme edges Vof the window sashes represented by llo-wer sash l are cut down in width to receive the sash strips 5 and S, the thickness of which compensatesfor the material removed from the edges of the sash thereby enabling the sash to be slidable within the longitudinally extendin'gstiles of the window frame and swingable transversely` of the stiles.

The opposite edges of the sashes are mortised as represented at l for receiving projectable and retractable weather stripping 3, cushioned against coil springs 9 and IU, which are arranged in' aligned sockets I l'l2 and ld-le in the inner edge or the weather stripping 3 and the mortise i of window sash l.

The window sash l is slotted at le to allow the passage of connecting member il which is secured to the rear of weather stripping 8. Connecting member Il is provided with an inwardly projecting porti-on having an angularly disposed slot I8 therein. The slotted portion i8 of the connecting member Il projects beyond the inner edge of the window sash l and is engaged by a transverse pin I9 carried by the manual operator 2Q.

The manualv operator 20 is centrally recessed at 2i for the passage of the inwardly projecting end c-f the connecting member Il, whereby upward movement of the operator 20 projects weather stripping 8 from the mortised recess 1, as shown in Fig. 5, whereas, downward movement of operator 2d retracts weather stripping 8 into the mortised recess l, as shown in Fig. 6.

Weather stripping 8 is centrally cut away, as represented at 22, for permitting the weather stripping 8 to extend on opposite sides of the hardware plate 23 which is secured centrally of the edge of window sash I. The hardware 23 carries an integral inwardly extending socket 24, of polygonal or square section. A similar socket is provided at each edge of the window sash and serves to receive the projecting end or stud 25 of the journaling hardware, shown more par` ticularly in Figs. l'i-l9.

The journaling hardware comprises a circular plate 2t, connected to the central polygonal or square stud 25, which enters the socket 24 at each side of the window sash. The plate 25 carries diame'trically opposed cam members 2l' and 28 which are movable on an orbit of approximately degrees. The journaling hardware is mounted within a recessed liner 2t shown more particularly in Figs. 2li-22, embedded within sash strip 5. Sash strip 5 has a central opening 3i) therein adapted to receive the recessed liner 29. The recessed liner 2e is cup-shaped in section having a pair of lugs 3i and 32, extending on diametrically opposite sides thereof and serving to secure the recessed liner in position with respect to the sash-strip 5, as shown. The recessed liner 29 has a diametrically extending slot 33 therein which is aligned with the groove 34 in the sashstrips, int-o which the weather strippingv 8 is adapted to project.

The cam members 2i and 28 extending from plate 25 normally project through -the slot 33 in liner 2S and gre-ove 3ft inthe sash-strips when the window sash is Ymaintained in a vertical Dosition for upward and downward sliding movement, in the stiles. This is accomplished by the registration of the polygonal or square stud 25 with the correspondingly shaped socket 24, as represented in Figs. 3, 5, 6, 7 and 8. However, when the sash is tilted through an angular pcsiticn which rotates cam members 2 and 28, against the inner faces of a recessed liner 29, as represented in Figs. 4 and 14, this results in the ejection of the plates '25" of the oppositely arranged journaling hardware simultaneously in opposite directions. The studs l25 are each slidable or adjustable transversely of the Sash in the sockets 2d. This results in the frictional gripping of the opposite sides of the frame A of the double-hung window inner faces which I yhave represented at 35. rhusr the window sashesa'fter being adjusted to a selected Vertical position may be substantially locked or restrained in position by tilting of sashes at an angle, thereby spreading the plates `2S of the journaling hardware inopposite transverse-directions for gripping the inner faces 35 ofv the window frame.

The sash strips 5 and 6 are each apertured at 36 and groo'Ved at 3l to receive the knotted ends of the sash cords 3S which operate over pulleys 39 through the frame of the window and connec'ted to sash weights d, which balance -the raising and lowering of the window sashes.

The window's'ashes carry Suitable glazingrepresented by glass panes 4I. The double-hung window sashes when in closed position may readily havethe weather stripping 8 which is carried thereby ejected into the aligned grooves 34 by moving the operators 20 upwardly as represented in Figs. 5 and 9 for thereby rendering the window tight against the entry of wind, rain, dust, sand or snow.

Throughout the specification I have restricted the explanation to one side of the window frame, as it will be understood both sides are symmetrical and that the explanation relates equally well to both sides. It will also be understood that tilting movement of the window sashes after vertical adjustment thereof to selected positions automatically locks or Xes the sash in the position to which it is adjusted by reason of the simultaneous outward movement of the plates 26 of the journaling hardware members. That is to say, the hardware members establish a tight t within the window frame when the sashes are in tilted position but assume a loose lit when the sashes are in vertical sliding position.

While I have described my invention in one of its preferred embodiments, I realize that modiiications and changes may be made and I intend no limitations upon my invention other than may be imposed by the scope of the appended claims.
